What can you say? Speed record (like ~25seconds) down Glacier Rondi in Chamonix. I believe there's a short section from the exit couloir in the end of the clip.
It maybe doesn't look pretty but think about speed and efficiency (on the righ person's feet).
If I had limitless ski days I'd go out on a mono once in a while just for the hell of it.
